**Note:** If you are developing a new action for `SocialAgent`, please
review the checklist below and mark all applicable items with an `x`. If
you're not adding a new action, you can skip this section.

- [ ] I have added the new action to `ActionType` in
[`typing.py`](https://github.com/camel-ai/oasis/blob/main/oasis/social_platform/typing.py).
- [ ] I have added a corresponding test or a similar function, as shown
in
[`test_user_create_post.py`](https://github.com/camel-ai/oasis/blob/main/test/infra/database/test_user_create_post.py).
- [ ] I have included the new `ActionType` in both
[`test_action_docstring.py`](https://github.com/camel-ai/oasis/blob/main/test/agent/test_action_docstring.py)
and
[`test_twitter_user_agent_all_actions.py`](https://github.com/camel-ai/oasis/blob/main/test/agent/test_twitter_user_agent_all_actions.py).
- [ ] I have documented the new action in
[`actions.mdx`](https://github.com/camel-ai/oasis/blob/main/docs/key_modules/actions.mdx);
the Mintlify GitHub app will deploy the changes automatically.
